MOSCOW: Russia's pole vault star Yelena Isinbayeva cruised to the national title on the second day of Russia's track and field athletics championships on Tuesday.

Isinbayeva cleared the 4.75-metre mark with her third attempt to finish 15 centimetres clear of second-placed Anastasia Savchenko. Angelina Krasnova was third with 4.50-metres.

Isinbayeva said she has almost completely recovered from the leg injury which prevented her from competing at several tournaments this season and was ready to compete at the world championships at Moscow's Luzhniki arena next month.

"My leg doesn't cause me inconvenience any more," Isinbayeva said. "I can jump almost at full strength. The doctors told me that my physical condition will improve for the world championships."

The 31-year-old pole vault queen added that after the Russian championships she was planning to return to her home town Volgograd to carry out final preparations for the worlds.
